Thread: Some Kind Of Horrible Noise.

UPDATE: Started my car today, The horrible screeching noise is gone. but i can hear my supercharger sounding like a machine gun. i know that's the coupler i have a spare but getting a hold of supercharger oil is pretty hard around here. i did notice while the car was running that it smelled like one of the belts was burning. but i didnt see any of the pulleys stopping or the belt slipping on
any of them.

Well if it had been just the supercharger belt's idler the plastic rim of it would have melted off it's seized bearing and shot out somewhere and the belt would have just fell off. If the belts are still on and all the pulleys are still spinning there may still be a good chance it's not the supercharger.

Take Bluemagic's advice and first remove the supercharger belt - the engine will still run just fine without it. If the noise persists suspect the alternator or power steering or AC pumps - superchargers do not imitate machine guns, they usually first howl or intermittently groan like banshees and/or just eventually seize up in death mode.

The only way a SC could lock, burn belts and then rattle would be if something metal got sucked into it.
